Carolina Hurricanes defenseman Tim Gleason is out with a concussion head coach Kirk Muller said on Monday.

Muller said Gleason suffered a concussion in the Sept. 21 preseason game against Montreal. Gleason 30 fought Jarred Tinordi at the 4:41 mark of the first period and though he played the remainder of the opening frame he did not return after the intermission.

“We’ll just go through the protocol and when the time is right we’ll get him back into action” Muller said.

In other injury news the Hurricanes placed Tuomo Ruutu on injured reserve on Sunday retroactive to Sept. 21. The forward is sidelined with a lower-body injury unrelated to his injured hip from last season and he is eligible to be activated at any point.

Alexander Semin (upper body) and Elias Lindholm (upper body) continue to skate with assistant coach Rod Brind’Amour and Muller isn’t ruling out their return in time for opening night.

“The next step is they get to stark working with the team and get practicing. They need to do that before they get into action with the team for games” he said. “We’ll watch them each day and see if they progress which they are right now.”

Initially Lindholm was penciled into the third-line center position. In his absence Riley Nash has jumped into that role with the same confidence he exuded last season. The upside of Lindholm? His versatility.

“He could play center on the third or fourth line. He could play the wing on either of those lines” Muller said. “It’s just a matter of who our personnel is to support him. I’m comfortable with him either playing center or the wing.”
